SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR INTERACTING WITH ELECTRONICALLY DISPLAYED PRESENTATION MATERIALS

摘要

Systems, methods, and computer program products for interacting with electronically displayed presentation materials are described. A display system includes, at least, a digital processor, an electronic display, and a non-transitory processor-readable storage medium into which is loaded a computer program product that includes, at least, processor-executable instructions and/or data. The processor-executable instructions and/or data, when executed by the processor, cause the display system to respond to user inputs indicative of pointer commands and magnification setting commands. In response to such commands, the display system causes; i) a dynamic cursor to display over top of content on the electronic display; and ii) a digital copy image of the content to be displayed over top of the content on the electronic display, the digital copy image displayed at a greater magnification level than the content.

主权项

1. A method of operation in a display system which comprises at least one processor, an electronic display communicatively coupled to the at least one processor, and at least one non-transitory processor-readable storage medium communicatively coupled to the at least one processor, wherein the at least one non-transitory processor-readable storage medium stores at least one of processor-executable instructions and data, the method comprising:
causing, by the at least one processor, a display of content at a first magnification level on the electronic display; receiving, by the at least one processor, a user input indicative of a magnification setting command; in response to the user input indicative of the magnification setting command: capturing, by the at least one processor, a digital copy image of the content; digitally magnifying, by the at least one processor, at least a portion of the digital copy image of the content; and causing, by the at least one processor, a display of the digitally magnified at least a portion of the digital copy image of the content at a second magnification level on the electronic display, the second magnification level greater than the first magnification level.
